Eye care and health are considered extremely important considering the ability to see is only possible using our eyes. If taken care of from a young age, there’s really nothing much to maintaining good eyesight. Unfortunately, only a small percentage give peepers due attention. A healthy diet, abstinence from habits and products known to ruin health and eyesight, as well as regular visits to the optometrist can guarantee eye health that lasts till the end of days. A complete checkup may include a list of tests such as the following: Fluorescein angiogram This test examines the blood circulation of eyes and is particularly helpful in diagnosing diabetic retinopathy, a condition that results from diabetes complications. Here, a dye called fluorescein is injected into a vein. When it reaches the eyes, a camera with special filters tracks its flow through blood vessels. Optometrists can then determine if a patient suffers from leakage or circulation problems signifying diabetic retinopathy. Refraction test A refraction test determines what eyeglasses a patient needs. It’s the test we’re most familiar with where the optometrist gives us a chart on which alphabets and numbers are contained. The clearer we’re able to see through various lenses, the better our eyesight is. Not only does the refraction test help prescribe lenses but it also helps diagnose conditions like myopia and hyperopia. A new type of refraction test called wavefront examination may also be used. It involves having a patient stare into a point of light and checking how light refracts when it passes through the eye. Applanation method Patients displaying symptoms of glaucoma or wanting to test for glaucoma undergo the applanation method. In the test, a dye is applied to the front of the eye using a strip of special paper. A device called a tonometer measures the pressure of air emitted to the eye. How resistant the eyes are to the puff of air indicates the presence or glaucoma or how extensively it’s invaded the eye. The applanation method is crucial in diagnosing the condition because glaucoma doesn’t show symptoms until loss of vision is significant. Hence, the earlier it’s detected the sooner treatment can be sought and blindness averted. Corneal and retinal topography Conditions like astigmatism, where the eye cannot bring an object into sharp focus, can be diagnosed with corneal and retinal topography. It’s not typically a part of routine eye examinations though it can be sought. The test can check for swelling, scarring and distortions that indicate astigmatism. It’s also used to evaluate eye health before patients go into eye surgery or are fitted with contact lenses. Slit lamp The slit lamp test can diagnose conditions like macular degeneration and cataracts. It examines both the front and back of the eyes using a slit lamp and a biomicroscope which displays a highly magnified view of various parts of the eye. An orange dye may also be applied to check for cuts and scratches if the instruments aren’t able to yield details in certain portions of the eye. A routine visit to the optometrist won’t entail all the tests given here but you can ask for them. Early detection of various conditions is vital to prevent compromised vision and in many cases, complete loss of vision. So, stick to regular optometrist’s appointments to prevent the development of debilitating diseases.
